Quantum computers—theoretical machines which can process certain large and difficult problems exponentially faster than classical computers—have been a mainstay of science fiction for decades. But actually building one has proven incredibly challenging. »3/21/15 6:04pm 3/21/15 6:04pm

I don't know when optical quantum computers are going to arrive, but I sure hope they look like this crazy Toshiba visualization of an Entangled Light Emitting Diode. This new LED type could finally make practical quantum computers possible. »6/11/10 5:20pm 6/11/10 5:20pm

In the future, quantum computers will accomplish in seconds what would take years with our best computers today. Physicists at NIST have made a significant leap towards this goal by demonstrating the first "universal" programmable quantum information processor. »11/18/09 11:44am 11/18/09 11:44am

Yale researchers just made the first, albeit simple, quantum processor. The processor is made of two artificial atoms (each made of a billion aluminum atoms) that act like single atoms that can occupy two distinct states. »6/29/09 3:40pm 6/29/09 3:40pm
